Been workin guys...sorry for not responding earlier.
Well boys, what ya got there looks like an HH-60D to me, but possibly an HH-60E. Back when the ole USAF first purchased the -60 they were A models without HIRSS. On a side note, USAF ARRS was on the way out as the boys with stars didn't think it was a valid mission anymore. We only got the -60 thanks to some 04's-06's that had enough foresight to realize that CSAR WAS a valid mission and did a little work-around. The blackhawk was already being brought on line by the Army, so they picked it with several modifications in mind. But more on that some other time if anyone wants to know.
Anyway, at first the Army -60's were having problems so the USAF put a hold on the project until the bugs were worked out. After this was resolved the USAF got their first compliment of Blackhawks from the Army and sent them off to Corpus Christi for the SAR mods. You might find it interesting that Sikorsky never did (and still really hasn't as far as I know) signed off on these mods. After all, the Blackhawk was never designed to be a CSAR Helo, rather a tough excellent assault helo. As I've told others on this forum the Pavehawk is kinda like taking your Ferrari on vacation and then bringing along the wife, kids, dog, mailman, etc..
I think the first operational Pavehawks were given to the 55th SOS down at Hurlburt Field, and by this time they were either A+'s or L models (in USAF parlance, H-60G's). Since they were an AFSOC unit, they got the mods for HIRSS and several other SOF specific requirements to include the internal aux fuel tanks, FLIR and such. Another side note is that the single station ESSS system was and has never been used operationally on USAF -60's, and for that matter I've never seen it used in training (my squadron has NEVER owned any and we came online in 1990). BTW, the Army ESSS system was never designed to be an operational system as well, rather it was designed as a ferrying system. Range constraints and troop inginuity incorperated them for tactical use. Hell, when they first used them up here in Alaska on the ARNG's Blackhawks, the fuel lines would freeze up. Crewdogs were forced to make them work by ducting bleed air around them (true story). Of course they changed this later on. The .50's in the main cabin doors deal was a 422 TES deal at Nellis and if you ever see a picture of one configured with them, dollars to doughnuts that's who owns the birds. The configuration is in the Dash-1 but we don't use it (for reasons I've already spoke of on this forum).
After the -60's started replacing the H-3 for USAF rescue units, there was a distinction which is pointed out in the Squadron book. However, several years after this transition, HH-60G's started being fitted exactly the same as AFSOC (55th SOS) MH-60G's with FLIR and miniguns (GAU-2's). Interestingly, my squadron was one of the first USAF CSAR HH-60G squadrons to get FLIR, but it wasn't purchased initially by the USAF. Our FLIR units were initially purchased by the DEA since we operationally assisted them looking for marijuana grow operations up here in Alaska (no kidding). We've always been able to put .50's in the windows, but just didn't do it much. We do it much more now, especially with the new external gun mounts.
So with the exception of the early years, an HH-60G is the same as an MH-60G. The main deal being that H signifies rescue (non-SOF) and M signifies SOF. The 55th SOS birds (while they had them) were called MH-60G's and the USAF CSAR unit's birds were HH-60G's. Remember when AFSOC took over USAF CSAR for a year or two recently? Guess what our Pavehwaks were referred to then...you guessed it...MH-60G's, that is of course if your squadron was realigned into AFSOC. My unit stayed in PACAF so we've always referred to ours as HH-60G's. Same deal for MC-130P's and HC-130P's.
Well, have I muddied this up or does that clear things up a bit? Realize that I'm on hour 11 of my last set of night alerts so bare with me.
Bottom-line, it's my opinion that that's an HH-60D or HH-60E. The HH-60E was the prototype for the HH-60G.
